WRENCH.

SPECIFICATION forming part of Letters Patent No. 583,217', dated May 25,189'?.

Application filed March 12, 1897. Serial No. 627,196. iNo model.)

To all whom t may concern.-

Beit known that I, RICHARD S. SAMPLE, a citizen of the United States,residing at Huntington, in the county of Cabell and State of VestVirginia,have invented certain new and useful Improvements in Vrenches;and I do hereby declare the following to be a full, clear,

Aand exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same.

My invention relates to improvements in wrenches, and more particularlyrefers to that class of wrenches which have the sliding jaw moved byscrew action; and such invention seeks more especiallyto provide asimple and inexpensive attachmentadapted to be secured to this class ofwrenches, which is capable of adjustment thereon in such a manner thatwhen moved in one direction the screw-sleeve will be held out of alocked engagement with the wrench-shank, whereby to admit of the saidsleeve and jaw being freely moved up and down on the shank, and, whenadjusted in another position, to hold the sleeve and sliding jaw lockedfrom movement.

My invention also seeks to provide an attachment for wrenches for thepurposes stated so constructed and arranged as to admit of its beingconnected to the class of wrenches of the kind stated without changingthe structure thereof.

With other objects in view, which will hereinafter appear, the inventionconsists in the peculiar combination and novel arrangement of part-s,such as will be first described in detail, and then be specificallypointed out in the appended claims, reference being had to theaccompanying drawings, in which- Figure l is a side elevation of awrench equipped with my improved attachment, the parts being in positionto admit of a free movement of the sleeve and sliding jaw. Fig.2 is avertical section, partly in elevation, of the same, the parts being in alike position as in Fig. 1. Fig. 3 is a detail edge view illustratingthe jaw held locked from vertical movement. Fig. 4 is a transversesection taken on the line 4401" Fig. 2. Fig. 5 isa top plan view of theattachment. Fig. Gis a side view, and Fig. 7 a perspective View7 of theattachment.

Referring now to the accompanying drawings,in which like numeralsindicate like parts in all the figures, 1 indicates the wrench-handle;2, the flat shank, having screw-notches 2n in the opposite edges, and 4the fixed jaw. 5 indicates the rotary sleeve, which has a centralcircular bore 5, extending its entire length, and at opposite sides arow of segmental cog-teeth 5b, as most clearly shown in Fig.4, whichwhen the sleeve is turned in one direction are h eld in .mesh with thescrew-notches 2a of the shank and when turned at right angles are heldfree of such screw-notches 2a, as shown in dotted lines in Fig. 4.

The upper end of the sleeve has the usual annular groove 7, whichextends entirely around and which receives the inturned tongue S on thependent members Sa of the sliding jaw, as clearly shown in Fig. 2. The

several parts and their combination may be of the ordinary form, and,per se, form no part of this invention.

My improvement comprises, essentially, a rotary sleeve or cuff member10, which is adapted to snugly fit the sleeve 5, its upper end having aninturned iiange 11 to bear on the upper reduced straight face 5c of thesleeve 5, while its lower end is held to encircle and slide verticallyon the large circular base portion of the sleeve 5, which has an annularbase-ange 5d to limit the downward movement of the cuff member 10. Thismember 1() is normally held forced toward its uppermost position, andfor such purpose the inner sleeve 5 has aportion of its body made of areduced diameter to provide an annular space 12 to receive a coil-spring13, which seats on the lower annular bearing-face 51of the sleeve andpresses up against the inturned flange of the member 10.

To cause the inner and outer sleeves to turn in unison, the inner sleeve5 has preferably at diametrically opposite sides vertical slots 14 toreceive the shanks 16a of the set-screws 1G, secured to the outer sleeveor cuff 10.

The upper end of the outer sleeve or cuff member 10 has three verticalprojections 14, 15, and 1G, two of which, 14c and 16, are arranged atapproximately diametrically opposite points, while the other, 15, whichis of less height than either the members 14C and 16, is at a pointintermediate of but nearest IOO the members 14c whereby to form arecess14, v

clearly in Fig. 3, and thereby hold the parts to lock in position, andin consequence the movable jaw in a fixed relation to the iXed one.

So far as described it will be readily seen that by pressing the outersleeve 10down so that the upper edge- 15 will be at a pointbelow thebottom of the pendent or hook portion of the sliding jaw, and' turningsuch sleeve in the direction indicated in Fig. 4, such sleeve and theinner sleeve willbe rotated to such a point as to bring the internal:rows of teeth into the` dotted position shown in Fig. 4, the rotation ofthe sleeves in such direction being limited by the projecting end 1 G,which the sliding jaw will engage. When in this position,the sliding jawand the sleeves can be moved freely upon the shank. After the slidingjaw has been adjusted to the po- ,i

sition desired the same is moved to a gripposition, the sleeves are heldfirmly in one hand as the wrench shank or body is rotated toward theleft, the pendent members of the sliding jaw forcing the outer sleeveslightly downward as it engages the incline until it engages theprojection 14C, when further movement thereof will be arrested and thespring serve to force the recess 14n of the sleeve over the pendent endotv the sliding jaw.

From the foregoing description, taken in connection with the drawings,the complete operation and the advantages of my invention will bereadily understood.

It will be observed the attachment is of such a nature that it can bereadily fitted upon any wrench of ordinaryconstruction ot" f It is of avery simple and economical nature and will positively the classdescribed.

serve for its intended purposes.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. In a Wrench of the kind described, an

attachment therefor, consisting of a rotary lbody connected with theshank-engaging sleeve, adapted, when rotated, to move the said sleeveinto a locked position with the Ishank, or free from engagementtherewith, iand arranged to hold such sleeve in such positions, as setforth.

2i. In a wrench of the kind described, the combination with the shank,the sleeve connected therewith and the sliding jaw connected with thesleeve, of a rotary member `connected to the sleeve and having a verti--cal movement thereon, said rotary member 1having' lock portions adaptedto engage the `sliding jaw and' hold it to its adjusted posi tions,substantially as shown and described. 3. In a wrench, the combinationwith the shank, the sleeve and the sliding jaw connected with thesleeve, of the outer rotary sleeve secured to turn with the innersleeve,

said rotary sleeve having vertical movement on the inner sleeve, andprovided on its upper edge with lock and stop portions to limit therotary movement of the Wrcnch-bodyand lock the sliding jaw to itsadjusted positions.

4. In a wrench as described, the combination with the shank, the innersleeve having segment cogs or teeth to engage the tooth- Eshank and anannular groove in its upper end, and provided with vertical slots, andthe l sliding jaw having a pendent member having :a iiange to engage theannular groove in the i' inner sleeve, of the outer rotary sleeve, said`sleeve having projections 14 15 and 16 at ythe top, a recess 14a and aninclined portion I connected with such projections, the screws securedto the rotary member and projected into the slots in the inner sleeve,and the j spring for holding the said outer sleeve forced normally`upward, all being arranged substantially as shown and described.

In testimony whereof I afiiX my signature in presence of two witnesses.
